Description

Technical Field

[0001] The utility model relates to a fan accessory, in particular to an iron-plastic composite fan support seat. Background Art

[0002] The fan support is a crucial component of the fan. Its primary function is to support the fan mainframe, ensuring stability during operation and withstanding vibration, wind force, and weight generated by the fan. In existing technology, the design and material selection of the fan support play a crucial role in the overall stability and safety of the fan.

[0003] Currently, most fan supports on the market are made of cast iron or cast aluminum. The advantages of these metal materials are high strength, ability to withstand large loads to a certain extent, and resistance to deformation. However, cast iron or cast aluminum structures also have some obvious disadvantages:

[0004] 1. High production costs: Cast iron and cast aluminum are relatively expensive materials, and the casting process is complex, requiring high-temperature melting and precision molds, resulting in high production costs. This poses a significant challenge for mass production or products requiring low costs, especially in the current market environment of fierce competition and strict cost control. This manufacturing method increases the overall cost of the product.

[0005] 2. Heavy weight: Although cast iron and cast aluminum support bases are strong, they are heavy, which brings inconvenience to transportation and installation. Especially for products that need to be moved frequently, such as household fans, the heavier support base increases the inconvenience during use and reduces the user experience.

[0006] To address these issues, some fan supports have begun to be manufactured using sheet metal bending. This method uses thinner sheet metal, forming the support structure through bending and folding processes. This structure reduces production costs and product weight to a certain extent, but it also has obvious disadvantages:

[0007] 1. Insufficient support strength: While bent metal support bases can reduce weight and cost to a certain extent, their relatively weak structure limits their ability to withstand wind and vibration during fan operation, making them prone to deformation or damage. Especially with prolonged and frequent use, the support base can become warped or loose, leading to unstable fan operation and potentially even safety hazards.

[0008] 2. Easy to deform: The thickness of metal sheets is limited. Although bending can enhance local strength, it is easy to cause permanent deformation when subjected to large stress. This will cause the fan support to lose its original stability and affect the normal use of the fan.

[0009] Therefore, existing fan supports, whether constructed from cast iron, cast aluminum, or bent sheet metal, often struggle to balance cost, weight, and strength. Fan supports for home or light industrial use, in particular, must maintain support strength and stability while controlling production costs and reducing product weight to enhance user experience. These factors have prompted a rethink of existing fan support structures and materials, seeking a more rational, economical, and reliable design. Utility Model Content

[0010] The purpose of the present utility model is to overcome the shortcomings of the existing technology and provide an iron-plastic composite fan support base with simple structure and easy use. It aims to optimize the structural design and combine the advantages of iron and plastic materials to provide sufficient supporting strength and effectively reduce production costs and weight, thereby overcoming the defects in the existing technology.

[0011] The purpose of the utility model is achieved by the following means: an iron-plastic composite fan support base, which includes a vertical pipe, a first hinge ear and a second hinge ear extending upward from the top of the vertical pipe, and a hinge area formed between the first hinge ear and the second hinge ear;

[0012] The invention also includes a support tube, wherein a reinforcement sleeve is provided on the cylindrical surface of the support tube, and a filling block is embedded and installed in the reinforcement sleeve, and the filling block fills the internal space of the reinforcement sleeve;

[0013] It also includes a hinge bolt. The reinforcement sleeve and the filling block are installed in the hinge area. The hinge bolt passes through the first hinge ear, the reinforcement sleeve and the second hinge ear to fix them in the hinge area.

[0014] Furthermore: the cross section of the reinforcement sleeve is arranged in a "C" shape, and both ends of the reinforcement sleeve are connected to the support tube.

[0015] Furthermore: the upper end of the reinforcement sleeve is connected to the cylindrical surface of the support tube, and the lower end of the reinforcement sleeve is arranged to cover the lower end surface of the support tube.

[0016] Furthermore, the lower end of the reinforcement sleeve is provided with an upwardly protruding positioning boss, and the positioning boss extends from the lower end surface of the support tube into the interior of the support tube.

[0017] Furthermore, the filling block is made of plastic material, and its outer contour is similar to the inner contour of the reinforcement sleeve.

[0018] Furthermore, a concave fitting surface is provided on one side of the filling block facing the support tube, and the fitting surface is closely attached to the outer cylindrical surface of the support tube.

[0019] Furthermore: the support tube is filled with an upper isolation sleeve and a lower isolation sleeve, and the vertical shaft of the fan host is installed in the upper isolation sleeve and the lower isolation sleeve to achieve connection with the support base.

[0020] Furthermore: the upper isolation sleeve is made of plastic material, and the upper end surface of the upper isolation sleeve protrudes from its cylindrical surface to be provided with a limiting platform, and the limiting platform is provided to cover the upper end surface of the support tube.

[0021] Furthermore: the vertical pipe is formed by bending a metal plate.

[0022] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0023] 2. The iron-plastic composite fan support proposed in this patent utilizes a design combining iron and plastic materials, avoiding the high-temperature smelting and complex casting processes required for traditional cast iron or cast aluminum supports. The plastic filler embedded within the reinforcement sleeve effectively replaces some metal components, reducing both metal usage and production complexity and cost. This composite structure simplifies the manufacturing process, making support production more economical and efficient.

[0024] 3. Compared to traditional cast iron or cast aluminum supports, this patented design significantly reduces the weight of the overall structure by using a combination of iron and plastic materials. Plastic is lighter than metal and reduces overall weight while maintaining support strength. This makes the fan support easier to transport, install, and use daily, enhancing the user experience.

[0025] 4. By placing a reinforcement sleeve on the cylindrical surface of the support tube and filling it with plastic fillers, this patented design enhances the overall strength of the fan support base. The "C"-shaped cross-section of the reinforcement sleeve increases bending and torsion resistance, and the plastic fillers fill the internal space, providing additional support and stability. This iron-plastic composite structure significantly improves the support base's compressive and impact resistance while maintaining its lightweight, effectively avoiding the deformation-prone shortcomings of traditional sheet metal bending structures.

[0026] 5. Because the filler block is made of plastic, it has excellent elasticity and shock absorption properties. When the fan is running, the plastic filler block can effectively absorb and cushion the vibration from the fan body, reducing the impact of vibration on the support base structure and extending the service life of the support base. In addition, this design also reduces the noise during fan operation, making it run more smoothly and quietly. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described below in conjunction with the accompanying drawings. A fan support base of iron-plastic composite type includes a vertical pipe 1, a first hinged ear 11 and a second hinged ear 12 extending upward from the top of the vertical pipe 1, and a hinged area 13 formed between the first hinged ear 11 and the second hinged ear 12;

[0031] The support tube 2 is provided with a reinforcing sleeve 3 on the cylindrical surface of the support tube 2, and a filling block 4 is embedded in the reinforcing sleeve 3 to fill the internal space of the reinforcing sleeve 3;

[0032] It also includes a hinge bolt 5. The reinforcement sleeve 3 and the filling block 4 are installed in the hinge area 13. The hinge bolt 5 passes through the first hinge ear 11, the reinforcement sleeve 3 and the second hinge ear 12 to fix them in the hinge area 13.

[0033] In one embodiment, the cross section of the reinforcement sleeve 3 is C-shaped, and both ends of the reinforcement sleeve 3 are connected to the support tube 2 .

[0034] In one embodiment, the upper end of the reinforcing sleeve 3 is connected to the cylindrical surface of the support tube 2 , and the lower end of the reinforcing sleeve 3 is arranged to cover the lower end surface of the support tube 2 .

[0035] In one embodiment, the lower end of the reinforcement sleeve 3 is provided with an upwardly protruding positioning boss 31 , and the positioning boss 31 extends from the lower end surface of the support tube 2 into the interior of the support tube 2 .

[0036] In one embodiment, the filling block 4 is made of plastic material, and its outer contour is similar to the inner contour of the reinforcement sleeve 3 .

[0037] In one embodiment, the filling block 4 is provided with a concave fitting surface 41 on a side facing the support tube 2 , and the fitting surface 41 is provided close to the outer cylindrical surface of the support tube 2 .

[0038] In one embodiment, the support tube 2 is filled with an upper isolation sleeve 7 and a lower isolation sleeve 6, and the vertical shaft of the fan host is installed in the upper isolation sleeve 7 and the lower isolation sleeve 6 to achieve connection with the support base.

[0039] In one embodiment, the upper isolation sleeve 7 is made of plastic material, and the upper end surface of the upper isolation sleeve 7 is protruding from its cylindrical surface to provide a limiting platform 71 , and the limiting platform 71 is provided to cover the upper end surface of the support tube 2 .

[0040] In one embodiment, the vertical pipe 1 is formed by bending a metal plate.

[0041] Working Principle: In this case, a core component of the fan support is the riser pipe 1, located at the center of the support. It bears the weight of the fan unit and supports the entire fan structure. Extending upward from the top of the riser pipe are a first hinge lug 11 and a second hinge lug 12, forming a hinge area 13 between these two lugs.

[0042] The hinge lugs provide attachment points for the reinforcement sleeve 3. A hinge bolt 5 penetrates the first hinge lug 11, the reinforcement sleeve 3, and the second hinge lug 12, securing each component within the hinge area 13 and thus achieving a secure connection between the support tube 2 and the riser 1. This design not only ensures overall structural strength but also provides flexibility for fan angle adjustment through the hinge bolt design.

[0043] The presence of the hinge bolt 5 allows the fan to be adjusted at different angles to meet the needs of different usage environments, improving the fan's ease of use. Through the design of the hinge ears and hinge bolts, the support base not only stably supports the fan but also provides flexible angle adjustment function to adapt to various usage scenarios, improving the fan's adaptability and ease of operation.

[0044] A reinforcement sleeve 3 is installed on the cylindrical surface of the support tube 2. Its cross-section is C-shaped, which improves the structure's bending strength and torsional resistance. Furthermore, a plastic filler block 4 is embedded within the reinforcement sleeve 3, completely filling the space within the sleeve.

[0045] The C-shaped reinforcement sleeve 3 strengthens the support tube 2, preventing deformation associated with bent sheet metal structures. When the fan is running, wind and vibration act on the support tube 2, and the reinforcement sleeve provides additional strength, preventing bending or deformation over time.

[0046] The plastic filler 4, inserted into the reinforcement sleeve, serves a dual purpose: cushioning and supporting. First, it withstands external pressure, effectively increasing the sleeve's compressive strength. Second, the plastic material's elasticity absorbs vibrations during fan operation, reducing their impact on the support base.

[0047] Through the combination of the reinforcing sleeve and the filling block, the support seat has excellent anti-bending and anti-torsion properties. Even under long-term and high-frequency use, it can still maintain structural stability and is not easy to deform.

[0048] At the same time, the elastic properties of the plastic filling block give the support base a good shock-absorbing effect, which can effectively absorb the vibration generated by the fan during operation, prevent the fan from generating excessive noise, and improve the fan's comfort and operating stability.

[0049] The hinge bolt 5 is a crucial connecting element in the support base. It penetrates the first hinge lug 11, the reinforcement sleeve 3, and the second hinge lug 12, firmly securing the support tube and riser 1 within the hinge area 13. The hinge bolt design not only secures the components but also allows the fan support base to be rotated and adjusted within a certain range of angles.

[0050] During installation, the hinge bolts penetrate the hinge lugs and reinforcement sleeves, tightly connecting the support pipe 2 and riser 1, forming a stable overall structure. Both the static weight of the fan and the dynamic loads generated during fan operation are effectively transferred to all parts of the support base through the hinge bolts, ensuring safe fan operation.

[0051] The hinged bolt design allows for a certain degree of rotation during installation, allowing users to adjust the fan's angle to meet varying airflow and space requirements. The hinged bolt ensures the fan's stability while allowing for adjustment between different angles, enhancing convenience and flexibility.

[0052] Furthermore: the interior of the support tube 2 is filled with an upper isolation sleeve 8 and a lower isolation sleeve 6, which provide a stable installation space for the vertical shaft of the fan main unit. The upper end face of the upper isolation sleeve 8 protrudes from its cylindrical surface, and a limit platform is provided to cover the upper end face of the support tube to prevent the vertical shaft from moving upward or being misplaced. The vertical shaft of the fan main unit is reliably connected to the support seat through the upper and lower isolation sleeves. The isolation sleeve not only provides a stable support position for the vertical shaft, but also effectively prevents the vertical shaft from shaking or offsetting during operation, thereby ensuring that the fan remains stable during operation. In addition, the upper isolation sleeve is made of plastic material, which plays the role of filling the interior of the support tube 2, so that the support tube will not be deformed.

[0053] Therefore, the existence of the upper and lower isolation sleeves not only enhances the stability of the vertical shaft of the fan main unit, but also effectively prevents the vertical shaft from moving up and down through the limit table, making the fan operation more stable and safe.

[0054] Furthermore, a positioning boss 31 is located on the lower end surface of the support tube 2 and extends upward into the interior of the tube. When the reinforcement sleeve 3 is installed on the support tube, the positioning boss ensures that the sleeve is precisely aligned and prevents positional shifting. The sleeve-type connection ensures a strong connection between the sleeve and the support tube, ensuring precise alignment and welding of the sleeve and the support tube during assembly.

[0055] In summary, the iron-plastic composite fan support of this application, through its use of an iron and plastic composite material design, achieves a good balance in terms of weight, cost, strength, shock absorption performance, and ease of installation. Its operating principle fully utilizes the high strength of iron and the lightweight and shock absorption effect of plastic materials. While maintaining the stability of the fan, it significantly improves the structural strength, shock absorption effect, and service life of the support, and is therefore suitable for widespread promotion and use.
